Body-Centered cubic (bcc)

- Like the Simple-cubic structure but with one extra
lattice point in the centre of the cube.
- Three vectors of length
*a*(cell dimension =*a*×*a*×*a*). - Vector angles are all 90º.

- Three vectors of length
- A body centred cubic (bcc) unit cell has two points
associated with it.
- The corner points 8×1/8= 1
- Centre of the cell = 1
- total = 2

- Monatomic bcc lattices obviously have a coordination number of 8.
